How to avoid “if” chains?

by

You can use an && (logic AND):

if (executeStepA() && executeStepB() && executeStepC()){
    ...
}
executeThisFunctionInAnyCase();

this will satisfy both of your requirements:

  • executeStep<X>() should evaluate only if the previous one succeeded (this is called short circuit evaluation)
  • executeThisFunctionInAnyCase() will be executed in any case
